As part of the Perma-X airborne campaign led by the Alfred Wegener Institute in 2021, we collected super-high-resolution multispectral imagery of permafrost landscapes with the Modular Aerial Camera System (MACS), developed by the German Aerospace Center. From these images, we photogrammetrically processed four-band orthophotos (blue, green, red, near-infrared) and digital surface models at very high spatial resolution of 20 cm, as well as photogrammetric point clouds in RGB and NIR. This data collection aggregates two data subsets of the Kobuk Delta, Alaska, covering approximately 80 km². All images were collected on 10 July 2021.
